{"product_id":"blue-hawks-eye-bracelet-natural-chatoyant-quartz","title":"Blue Hawks Eye Bracelet — Natural Chatoyant Quartz","description":"\u003cp\u003eHawks eye is the blue-grey member of the chatoyant quartz family, and it formed the same way as golden tiger's eye: blue crocidolite fibres were replaced atom by atom with silica while the fibre structure stayed intact. The result is a bead with a narrow band of light that sweeps across as the stone turns. Quartz measures 7 on the Mohs scale, so it takes a high polish and holds it.\u003c\/p\u003e\n\u003ch2\u003eWhat you receive\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Natural hawks eye (chatoyant quartz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet type:\u003c\/strong\u003e Single loop, elastic, no clasp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Approx. 15-18 cm (5.9-7.1 in) wrist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e 7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout hawks eye\u003c\/h2\u003e\n\u003cp\u003eHawks eye is the blue-grey member of the chatoyant quartz family. It formed when crocidolite, a blue asbestos mineral, was replaced atom by atom with silica while keeping the fibre structure — the same process that produces golden tiger's eye, only the parent fibre was blue rather than golden. The shimmering band of light across the bead is a reflection off those parallel fibres, not a coating. Quartz measures 7 on the Mohs scale, so the bead is hard and takes a high polish.\u003c\/p\u003e\n\u003ch2\u003eFit and sizing\u003c\/h2\u003e\n\u003cp\u003eIt is a single loop, elastic bracelet on elastic with no clasp, and fits approx. 15-18 cm (5.9-7.1 in) wrist. Because the core is elastic it rolls on over the hand, so there is nothing to fasten one-handed. If you need a specific length, message us before ordering and we will tell you what is in stock.\u003c\/p\u003e\n\u003ch2\u003eCare\u003c\/h2\u003e\n\u003cp\u003eWipe with a soft damp cloth. The fibre structure is sealed inside quartz, so the surface is stable, but avoid sharp knocks that could chip an edge, and store separately from diamonds or sapphires.\u003c\/p\u003e\n\u003ch2\u003eShipping and returns\u003c\/h2\u003e\n\u003cp\u003eOrders are processed in 1-3 business days from our Shenzhen studio.

Deep saturated blue tiger’s eye sold in the trade is often heat-treated to shift the tone, so if strictly untreated colour matters to you, ask before ordering and we will tell you what we can confirm for the batch in stock.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between hawks eye and tiger's eye?\u003c\/h3\u003e\n\u003cp\u003eThey share the same structure. Tiger's eye formed from golden crocidolite fibres, hawks eye from blue ones; in both cases silica replaced the fibre and left the chatoyant band behind.\u003c\/p\u003e\n\u003ch3\u003eHow does it fit?\u003c\/h3\u003e\n\u003cp\u003eSingle loop on elastic, roughly 15-18 cm (5.9-7.1 in), no clasp to fasten.\u003c\/p\u003e\n\u003ch3\u003eHow do I clean it?\u003c\/h3\u003e\n\u003cp\u003eWipe with a soft damp cloth.
